Hi Steve,
Hmmm, thanks for confirming what I pessimistically suspected but
optimistically hoped to be corrected on. Unfortunately our data files
are frequently in the 3-4Gb range so it sounds like SFU is unlikely to
be an option either.
Would like to persist with cygwin as we use it for some of our
proteomics tools. I guess I'll have to ditch the security and try
rsyncd (just as soon as I can get on the client machines and add yet
another exception to the Windoze firewall) – unless anyone else has
any thoughts or suggestions?
Cheers,
Fred.

rsync over ssh and cygwin don't play nice and likely never will.
Either
avoid using rsync or use it in daemon mode avoiding ssh which is where
the problem really lies ( the interaction between rsync and ssh ).
A good alternative to cygwin for this is SFU but be aware that most
versions only support 32bit files so less than 2GB.

Steve

Good afternoon all,
Please excuse my cygwin newbie status if I have missed something
obvious.
Having resolved the "overly long file name" issue with rsync in
cygwin 1.5 by upgrading to version 1.7, I have hit a new problem,
namely rsync hanging midway through transfer. No errors are
reported or logged, nothing seems to be timing out, it just sits
there indefinitely. Re-running rsync will maybe do a couple more
files then hang again, and again, and again... Having read around
tinternet, it seems I am not completely alone in this problem, but
I have yet to find a solution that works for me. Briefly:
I have set up ssh-keyless authentication between my server (OsX
10.5.5, rsync 3.0.4, OpenSSH 5.1p1) and a dozen or so PC's running
XPsp2 (cygwin 1.7, rsync 3.0.4, OpenSSH 5.1p1) and use rsync to
mirror user directories on the PC's to my server, as follows:
rsync --verbose --progress --stats --rsh=/usr/bin/ssh --archive \
[EMAIL PROTECTED]:"/cygdrive/c/Documents\ and\ Settings/
userdirectory/" /Users/userdirectory/
This is in effect identical to the method I use to mirror data
between two OsX servers, where it can happily handle several
terabytes of data and millions of files. I have tried rsyncing
individual subdirectories in a userdirectory and that works fine
but still it hangs when the whole directory is tried again.
Similarly, one or two of the smaller user directories (around
15,000 files and 35Gb data) work fine. Over around 30,000 files
seems to be where I have the problem...
What is really strange is that if I run the rsync from the client
PC to the server, it works fine, and subsequent rsyncs from the
server also work fine (presumably since hardly any files have
changed)...
At this stage I am somewhat stumped and would appreciate any
pointers the gurus can give, even as to whether this is believed
to be an rsync, sshd or underlying cywin issue... Very happy to
provide further info as required, or to be shot down in flames
should I have done something stupid! ;-)
Thanks in advance,
Fred.
